Abstract

An embodiment of a semiconductor package apparatus may include technology to process a single stream of video frames which includes frame information from two or more video sources, and process a current frame based on information from a prior frame in the single stream of video frames which precedes the current frame by a number of frames based on a number of video sources represented in the single stream of video frames. Other embodiments are disclosed and claimed.

Claims

a processor;

memory communicatively coupled to the processor; and

logic communicatively coupled to the processor to;

process a single stream of video frames which includes frame information from two or more video sources, and

process a current frame based on information from a prior frame in the single stream of video frames which precedes the current frame by a number of frames based on a number of video sources represented in the single stream of video frames.

2. The system of claim 1, wherein the logic is further to:

process each sequential frame in the single stream of video frames as originated from a different one of the two or more video sources.

3. The system of claim 1, wherein the logic is further to:

determine a frame position of the prior frame based on a frame position of the current frame minus the number of video sources represented in the single stream of video frames.

4. The system of claim 1, wherein the logic is further to:

determine a video source position of a frame based on a frame position of the frame modulo the number of video sources represented in the single stream of video frames.

a substrate; and

logic coupled to the substrate, wherein the logic is at least partly implemented in one or more of configurable logic and fixed-functionality hardware logic, the logic coupled to the substrate to;

process a single stream of video frames which includes frame information from two or more video sources, and

process a current frame based on information from a prior frame in the single stream of video frames which precedes the current frame by a number of frames based on a number of video sources represented in the single stream of video frames.

8. The apparatus of claim 7, wherein the logic is further to:

process each sequential frame in the single stream of video frames as originated from a different one of the two or more video sources.

9. The apparatus of claim 7, wherein the logic is further to:

determine a frame position of the prior frame based on a frame position of the current frame minus the number of video sources represented in the single stream of video frames.

10. The apparatus of claim 7, wherein the logic is further to:
